Aluminum, especially when alloyed with one or more of several common elements, has been increasingly specified and used in packaging, architectural, transportation, chemical, electrical and many general applications. Today, aluminum is surpassed only by steel in its use as a structural material. The properties of aluminum and its alloys which give rise to their widespread usage, with particular emphasis on manufacturability, recyclability, and corrosion resistance, are briefly described in this report. The designation system by which alloys are classified is also described, and references are provided for the reader who may desire more detailed information.
